Exostosin-1 (EXT1) is an ER-resident glycosyltransferase known to polymerize heparan sulfate chain by sequential addition of glucuronic acid and N-acetylglucosamine molecules. This reaction results in heavily glycosylated proteoglycans (PG) at the plasma membrane, which form cell-type specific compl...
